bro can you explain the logic behind it @akashdeep18

LCM is not O(1), especially if your numbers are having like 1000+ digits. Try breaking after your LCM reaches the upper limit.

I first calculated the lcm of all the values in the rebel army, then i tried to find out the first multiple of lcm in given range of kings army(stored it in s) and then the final multiple of lcm(stored it in e), and then I found total multiples of the lcm in given range(by using c=((e-s)/lcm)+1 and stored in c) by e then I subtracted c from total no. of soldiers in kings army.@karun369

Thankyou @arvindpunk your suggestion helped got AC.
